Can't connect Mega [URGENT]

Hi,

I have a problem with my mega.

Until few days without connecting to my PC (only working what it should) my Mega was working fine. Today I tried to do some make up to my program, but I can't connect my Mega to any PC. I have tried different cables, different PC etc...

The board is reciveing power and running program, but I can't get it found by PC. No changes has been made. There is no sound for new device connected.

Do you have any idea?

Please help me.

Thank you

Faulty cable, bad connectors?

I will presume you disconnected everything from the board at some point before trying to upload ?

Damaged board or bad (charging only) USB cable. There has been a recent plague of crap cables impacting a lot of makers.
